Help with list picker

As you can see in the photo i have created a list where i can write stuff down and then pick them from a list picker and i can keep notes on each stuff . I set each element in list picker as index 1/2/3 etc. The problem is that every time I use the delete button to delete the element the index is not removed as wet and i can still tap it even though there is not text. Any thoughts?

Here is how deletion is done in a ToDo app that keeps separate lists for ToDo and DONE:
when Screen1 Initialize
Keep the .SelectionIndex from the List Picker, to remember which index was selected from the task list. I use a Label.Text.

I keep my ToDo items in a single list under TinyDB tag 'TODO'.
Only my two procedures shown here know that, and I let them control all access to list storage.

Will that work in my case? Also where do i find the call command ?

these are procedures, see also MIT App Inventor Procedure Blocks
